Meijer has entered into a pilot program with the state that will allow commuters to use designated areas of the Grand Rapids-based retailer's parking lots at six Michigan stores for car pooling.
Michigan's network of 231 car pool lots are used by 3,900 vehicles each weekday.
The state announced Friday that 300 new parking spaces will be available at Meijer Inc. stores in Kent County's Cascade Township, Lowell, Brighton, Jackson, Macomb County's Chesterfield Township and Auburn Hills.
Michigan Department of Transportation spokeswoman Dawn Garner says it costs the state between $200,000 and $400,000 to build each new lot.
The only expense under this program is $100,000 for road signs directing motorists to the six lots.
